4-WAY BEE ESCAIPEz'f a citizen of the United States, and resident. of Watertown, in the county of Jefferson and State of. Wisconsin, have inventedv certain new and-useful Improvements in a lvay Bee Escapes; and I do hereby 'declare'that the. following is afull, clear, and exactdescrip tionthereof.

My invention refers to 4-way bee escapes, particularly of that type such as disclosed in my application for Patent, filed June 29th, 1920, Serial No. 392658.

The object of my present invention is to simplify the construction of 4-way bee escapes, whereby the cost of manufacture is cheapened, and to also produce a device wherein accuracy as to dimensions of the escape openings is assured.

Specific objects of my invention are:

To provide an apertured base plate, the walls of the aperture being formed with integral clips.

To form the clips of a width equal to the width of apex sections constituting the central portions of V-shaped spring members, which form yieldable walls of the bee escapes, such construction rendering the positioning of the free ends of the springs accurately with relation to the fixed walls of a runway housing.

To dispense with soldering of the separable parts, whereby they may be cheaply and accurately assembled by positive clinc er connections.

With the above and other minor objects in view, the invention consists in certain peculiarities of construction and combination of parts, as are hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings:

Figure 1 representsv a longitudinal sectional elevation of the features of my invention.

Figure 2 is a bottom plan view, with parts broken away and other parts in section to moe clearly illustrate structural features, an

Figure 3 is a cross section of the same, the section being indicated by line 3-3 of'Figure 2.

Referring by character to the drawings, 1 represents a flat rectangular base plate having sets of elongated perforations 2 and Application filed. May 23,

a central'circular ingress opening 3. The wallsofthis opening, upon opposite sides,

and longitudinally of the plate, are stamped out to=form clips. 4:, which clips are folded.

upon themselves to firmly grip flat apex stretches 5 of V-shaped springs whereby the spring members are assembled. Owing-to the fact that the fiat stretches of the spring are the same width as the clips, they will be accurately centered with relation to the side walls 7 of a runway housing.

The runway housing is formed from a single blank, with its edges folded up wardly to develop the side wall 7. The bottom 8, which connects the side walls, forms the floor of an otherwise open ended runway housing. The flanged edges of the runway housing have integral clincher burrs 9 extending upwardly therefrom, which clincher burrs are adapted to enter the perforations 2 of the base plate. The said burrs are divided and folded over the uppersurface of the base plate in opposite directions to thus firmly rivet the housing in accurate position with relation to the yieldable ends of the V- haped springs, wherebysaid yieldable ends, in connection with the walls, form choked entrance throats of four runways, whereby the bees enterin the base plate opening will travel toward the ends of the runway, and as they pass through the restricted throats, pand so that the bees cannot return.

It is understood that the legs of the springs will divide the depth of the runway in such manner that bees cannot climb over or under said springs in their travel to the discharge ends of said housing. Thusit will be seen that a simple and accurate device is produced, whereby the parts, when assembled, do notrequire any soldering, and owing to the interlocking assemblage of the various parts, they will come together accurately so as to develop the proper dimensions of runway throats in connection with the ends of the springs and side walls of the housing.

I claim: I

1. A 4-way bee escape comprising a centrally apertured base ,plate, looped clips constituting part of the base plate and ex tending from the edge walls of the aperture,

a V-shaped spring having a fiat apex stretchthe ends will yield and exrunway having side flanges attached to the base plate, the side walls ofthe-runwayin connection with the free ends of the springs forming choked entrance passages,

2. A 4-way bee escape comprising a centrally apertured base plate, the edges of the aperture being extended at two points to form foldable clips, the said base plate be ing provided with sets of aligned performtions, V-shaped springs having fiat apex stretches fitted into the clips, whereby they are secured, and an open ended runway having flanges terminating with clincherburrs stricted throats in connection with the free ends of the springs.

3 .A 4-Way beeescape consisting of a base plate made of one thickness of metal having a central aperture, a pair of metallic strips adjacent said aperture integral with said base plate and directed at right angles thereto then bent and extending back S'l1b' stantially at right angles to the base plate and formlng a pair of loops,'apair of V- shaped springs, each having a fiat apex strip In'testimony that I claim the foregoing I a have hereunto set my hand at Watertown,

1n the county of Jefferson and State of Wisconsin.
